Span Calculator for Headers

What is a Span Calculator for Headers?

A “Span Calculator for Headers” is a tool used to determine the minimum required size (depth and width) of headers or beams used in construction to support a specific load over a defined span.

It helps ensure structural integrity and safety.

Why Use a Span Calculator for Headers?

• Structural Integrity: Headers must be strong enough to support the loads they will carry.
• Compliance: Ensures compliance with building codes and regulations.
• Cost-Efficiency: Helps avoid over-sizing headers, which can be costly.

How to Use a Span Calculator for Headers:

1. Enter the total load in pounds that the header will support.
2. Choose the wood species from the dropdown list.
3. Enter the on-center spacing of the headers in inches.
4. Click the "Calculate Header Size" button.

The calculator will display the minimum required header size in inches (depth x width).

Example Calculation:

Suppose you need a header to support a total load of 5,000 pounds with a 16-inch on-center spacing, and you choose Douglas Fir-Larch as the wood species.

The calculator estimates that the minimum required header size is approximately 15 inches (depth) x 15 inches (width).

This ensures that the header can safely carry the specified load over the given span.
